Controlling Indicator line width

[Rydo111]

Hi @kernc ; I love your work on this module; using it a lot lately. I have come across the need to control line width for each Indicator. I couldn't work out how to do it natively, so I tinkered with the code and it seems to work.

• added the line_width=None property to the def I() function
• added to the def _plot_indicators() function (under the colors instrcutions):
  line_widths = value._opts['line_width']
if line_widths is None:
line_widths = [2] * max(len(value._opts['color']), 1)
line_widths = cycle(_as_list(line_widths))

...then added to the for loop (again, under the color instruction):
line_width = next(line_widths)
...then added line_width=line_width to the fig.line function.

Not sure whether this is a dumb idea or not, but it seems to work. I can now control the line thickness of each of my plots. Just thought I'd share.

Regards,

Rydo
